MIXTURE-CONTROLLING MEANS FOR MOTORS.

manner.

gheny and State of Pennsylvania, have made a new and useful Invention in Mixture- Oontrolling Means for Motors, of which the following 1s a specification. i

This invention relates to explosion motors in which the charge consists of a mixture of air and some suitable combustible, as for example, gas.

An object of the invention is to var the pro ortions of air and gas in aecor ance '15 wit the change in qualit of the gas. For

' example, if the as is rim 0. larger proportion of air may e mixed with it than if it is lean. I

Another object of the invention is to pro- 2'0 vide means external to the primary or main engine or engines for controlling the mixture which said engine or engines is to use.

It has been found that the heat value of gas, one of the component elements of an explosion mixture, is liable to vary and it" ,measured charges of air and gas are introducedinto the combustion chamber of the engine, the explosion impulses of the motor are liable to vary in accordance with the 80 change in the mixture due to the change in the qualit of asfi For example, during a ven period t ere is liable to bee wide v riation of the quality of gas generated by a gas reducer. When the pro ucer is first '35 starte the gas will not be so rich as it is after the producer has been running for some time. There are other conditions confronted in actual practice which cause a variation in the quality of the gas during '40 a given period but these need not be considcred here. It will be apparent then that if the same proportions of air and gas were measured into the gas engine when the gas producer .was first started, after the proucer had been running for several hours' the: mixture would be greatly enriched,therefore there would be a varia ion in the power -of the motor due to this cause unless the mixing'valve was manipulated to decrease theproportion of gas and increase the pro- Specification of Letters Patent.

change in the port areas of the ports or valves comnuuncatmg with the combustion chamber or mixing valve of the primary engine.

A convenient physical embodiment of my invention may consist of a pilot engine of relatively low capacity and relatively high speed, operatin under constanhload and controlling mec ianism which will vary the proportions of air and gas admitted to the primary en ine of relatively large capacity and relative y low rotativc speed. The speed responsive device or governor of the pilot engine may be connected through suitable mechanism to an oil relay which actuates the mixing valve of the primary engine as.

well as the mixing valve of the pilot engine. The mixing valves of the, primary engine and the pilot engine are connected by suitable means so that any change in the quality of the gas is transmitted through the speed responsive device to the oil relay, then to both mixing valves. Inasmuch as the pilot engine isdesigned to have a higher speed than the primary engine it will re spond more quickly to changes in gas value and control the port areas leading to the primary engine or engines so that the speed of the primary engine will not appreciably change due to the variations of the gas value because the pilot engine will be sensitive enough and act quick enough to change the port areas for the primary engine or engines before any ap reciable change in speed may take place. he pilot en ine need necessarily ,only belarge enougi to operate the oil relay and move the'mixing valve of the primary engine or engines.

In the drawings Figure 1 is a longitudinal elevational v'ew of my invention; Fig. 2 is a longitudinal elevational view, the mixin chamber of the pilot engine and the oil re ay being shown in section, and Fig. 3 is a sectional view on the line 3-3 of Fig. 2.

The pilot engine is to carry an ap proximately constant load and is provided with the msual air and gas valves U and 7. In the pifegsent instance the air valve Unis li'austs back to justcrl so as to be caused to assume 21' fixed position and provide a constant air port area while the gas inlet port area may be varied by the speed responsive device 8 on the she/ft 9. A lever 10 is fulcrun'ieil to a bracket 11 and is engaged by the eolle r 12 of the speed responsive device, one entl oi said level. having connection with s lint: 13 in pivotal eonnection with a swinging rocking lQVtTS 1% connected to the valve i, The drive shaft 15 of the motor l i vided With a pulley l6 driving the of an air compressor 18 .337 moons of belt pipe and pemnits'the oil to circulate without entering the relay 926.
